Removal of ksaneplugin from KDE Applications

[Alexander Potashev]

Hi,

The only user for ksaneplugin used to be Kolourpaint in KDE
Applications 15.08.x. I have now ported Kolourpaint from KScanDialog
to libksane as suggested here [1,2] (same thread), thus ksaneplugin
can be dropped from KDE Applications 15.12.

BTW, is Kolourpaint ready for KF5 releases? I guess the only
showstopper is qimageblitz-qt5 being unreleased.
